Patent CA-2118501-A1 (CA)
Title: Imageable articles having dye selective interlayers
Inventor: PREMENTINE GLENN S
IPC: G03C8/52
Filed: 1993-01-29
Abstract: Imageable articles having dye selective interlayers comprising copolymers of styrene and vinylidene chloride are disclosed. The interlayers have sufficient permeability to be useful for constructions in which cationic dyes must be prevented from diffusing away from an image receiving layer. Additionally, the selective interlayers allow unoxidized leuco dye to be diffused away from an image receiving layer, thereby increasing print stability. Use of these interlayers in multicolor dye-diffusive imaging constructions increases image stability and color density in the final image.

Title: Thermoplastic elastomer composition
Inventor: KUBO JUNICHI
IPC: C08L95/00
Filed: 1994-11-30
Abstract: A thermoplastic elastomer composition is provided which is highly durable and free from oxidative deterioration when exposed to elevated temperature as in molding and also ambient temperature at which an end product thereof is used.  These advantageous features are attributable to the use of a hydrogenated oil of the class disclosed which serves effectively to suppress the tendency of an elastomer undergoing gelation or cross-linking particularly when heated in the atmosphere.  The hydrogenated oil is derivable from hydrogenation of a liquid product resulting from thermally treating a coal tar or distillates thereof at above 400°C; a liquid product resulting from thermally treating at above 400°C a petroleum crude oil, distillates thereof, or a liquid hydrocarbon derived from catalytic cracking, hydrogenative cracking or catalytic reforming of petroleum distillates; or a thermally cracked tar resulting from thermally cracking a petroleum crude oil or distillates thereof.

Title: Graphical environment for constructing systems
Inventor: SELFRIDGE PETER GILMAN
IPC: G06F15/00
Filed: 1995-06-28
Abstract: Apparatus for constructing a complex artifact out of primitive artifacts and other complex artifacts. The apparatus has a permanent knowledge base of primitive artifacts, previously-made complex artifacts, and rules defining how complex artifacts are made from primitive artifacts.  All artifacts in the permanent knowledge base have been checked for consistency. Artifacts from the permanent knowledge base are displayed in a search area as directed graphs in which the artifacts are represented by nodes. A user may search the permanent knowledge base, and the directed graphs in the search area show the results of the search. To construct a new complex artifact or to add to a complex artifact under construction, the user selects nodes of the directed graphs which represent desired component artifacts. Information about the desired artifacts is copied from the permanent knowledge base to a working knowledge base and a directed graph of the contents of the working knowledge base is displayed in a work area.  When information is added to the working knowledge base, consistency checks are made using the rules and the information in the permanent knowledge base. The results of the consistency checks appear in the display in the work area. A user may store an artifact under construction in the permanent knowledge base. A mapping editor permits the user to determine how object artifacts are mapped to the displays of the directed graphs.
Patent CA-2153723-A1 (CA)
Title: Lightweight Truck Sideframe
Inventor: SPENCER CHARLES P
IPC: B61F5/52
Filed: 1995-07-12
Abstract: A lightweight, cast steel railcar truck sideframe is the result of matching stress levels within each of the sideframe components with an amount of metallic mass necessary to maintain structural integrity during railcar loading. Areas on each component which were found to be low stress accumulation areas have removed mass from them, reducing sideframe weight. The removal of mass is accomplished by adding lightener holes to and/or reducing thickness of the particular component. Areas on each component found to be high stress areas have added mass in order to strengthen the sideframe. Areas with reduced mass far exceed those increased. The lightener holes are uniquely used in the casting mold such that only nine cores are needed when casting the entire sideframe. By using only a total of nine cores instead of twenty-eight, substantial manhour and production costs savings are realized. The nine core mold also improves internal and external casting quality through the stabilization of core geometry, elimination of seam lines and stress riser locations, which means that there will be far less of a chance for defects to occur.

Title: Methods for improving therapeutic effectiveness of agents for the treatment of solid tumors and other disorders
Inventor: DEWHIRST MARK W
IPC: A61P35/00
Filed: 1994-05-23
Abstract: The present invention is directed to the use of an inhibitor of NO activity, such as a nitric oxide scavenger or an NO synthase inhibitor, as an antitumor therapy to reduce tumor blood flow and oxygenation. The invention is also directed to administration of a nitric oxide scavenger or a nitric oxide synthase inhibitor to enhance the effectiveness of tumor therapy with hypoxic or acidic chemotherapeutic agents or hyperthermia. The invention is also directed to the administration of a nitric oxide synthase substrate to a subject previously administered a nitric oxide synthase inhibitor, in order to selectively inhibit tumor perfusion. In a specific example, administration of cell free hemoglobin, a nitric oxide scavenger, in conjunction with mitomycin C, a hypoxic cytotoxin, results in a significant delay in tumor growth of a human tumor xenograft in a mouse compared to mitomycin C alone. In another example, the administration of an inhibitor of nitric oxide synthase followed by the administration of a substrate of the enzyme causes a specific irreversible reduction of tumor blood flow, while normal blood flow is restored.
